Description
Technical Field
The present invention relates to a vibration size adjusting device and a camera shake correction function inspection device using the same, and more particularly, to a vibration size adjusting device capable of easily adjusting the size of vibration provided to a camera module for inspecting a camera shake correction function, and a camera shake correction function inspection device using the same.
Background
Recently, the demand for high quality images of cameras is rapidly increasing. The image of the camera may be degraded due to shake, such as image distortion. That is, phenomena such as blurring (blur), resolution degradation (resolution reduction), and sharpness degradation (sharpness reduction) caused by shake during image capturing become elements that degrade the image quality of a camera. Such shake may include camera shake due to shake of the hands of the photographer, shake of the subject, and the like. Further, the slower the shutter speed (shutter speed), the greater the degradation of image quality due to jitter due to the degradation of frame rate (frame rate) characteristics. At this time, when the surrounding environment becomes dark, the internal processing (processing) speed for increasing the brightness of the subject viewed from the camera becomes slow, eventually resulting in a slow shutter speed (shutter speed).
In addition, recently marketed cameras are generally internally provided with a shake correction device (Optical Image Stabilizer) which reduces degradation of image quality by correcting image distortion caused by shake. In addition, in actual cases, it is possible to correct how much the degradation of image quality caused by shake, that is, shake correction performance, is an important criterion for evaluating camera performance.
A method of providing vibration to a camera module using a hexapod (hexazpod) as in patent document 1 has been proposed in the past. Although such a hexapod animal can provide precise motions of six degrees of freedom in total including a linear axis of X, Y and Z and a rotational axis of θx, θy, and θz on one stage, there is an advantage in that a vibration direction required in an examination can be freely selected, but there is a problem in that a stroke limit is large, rapid vibration is difficult, and a unit price is also high, so that it is difficult to perform an effective examination.
Therefore, there is a need for an inspection apparatus that can effectively inspect the correction performance of a camera or shake correction apparatus that has been fabricated, when the inspection apparatus is close to the actual situation.

Detailed Description
Before describing the present invention, it is to be noted that in the embodiments, the same reference numerals are used for members having the same structure, and a representative description is given in the first embodiment, and a description is given in other embodiments for structures different from the first embodiment.
Next, a vibration level adjustment apparatus according to a first embodiment of the present invention and a camera shake correction function inspection apparatus using the same will be described in detail with reference to the accompanying drawings.
In the drawings, fig. 1 is a perspective view of a vibration size adjusting device of the present invention, and fig. 2 is a perspective view showing a rotating block and an eccentric block in fig. 1.
The vibration size adjusting device 100 of the present invention shown in fig. 1 and 2 includes a rotating block 110, an eccentric block 120, a connection guide 130, an eccentric adjusting portion 140, and a first driving portion 150.
In the present embodiment, the first axis direction, the second axis direction, and the third axis direction may be set to be orthogonal to each other, and although the first axis is denoted as an X axis, the second axis is denoted as a Y axis, and the third axis is denoted as a Z axis in the drawing, this is not a limitation.
The rotating block 110 may be formed of a cylinder type extending in the first axial direction, and a surface facing the eccentric block 120 may be formed of an inclined surface.
The eccentric mass 120 may be formed of a cylinder type extending in the first axial direction, and a surface facing the rotating mass 110 may be formed of an inclined surface parallel to the inclined surface of the rotating mass 110.
The connection guide 130 may include: a connection shaft 131 disposed on the inclined surface of the rotation block 110 and extending in a direction having a predetermined inclination angle with respect to the first axis direction; and a guide 132 disposed on the inclined surface of the eccentric block 120 for guiding the axial movement of the connecting shaft 131, wherein the guide 132 may be disposed in an insertion hole 121 formed in a recess on the inclined surface of the eccentric block 120.
Here, the rotating block 110 may be moved in an axial direction of the connecting shaft 131 toward or away from the eccentric block 120 connected by the guide 132, and in this process, an eccentric amount of the eccentric block 120 with respect to the rotating block 110 may be adjusted according to a spaced interval between a central axis of the rotating block 110 and a central axis of the eccentric block 120. In a state where the inclined surface of the rotating block 110 and the inclined surface of the eccentric block 120 are in close contact with each other, it is preferable that the center axis of the rotating block 110 and the center axis of the eccentric block 120 are disposed on the same axis.
The guide 132 may be formed of a bush (bush) that supports the connection shaft 131 so as to be axially movable, or may be formed of an elastic member such as a ball plunger that elastically supports the outer side surface of the connection shaft 131 on the inner wall surface of the insertion hole 121.
In addition, the connection shaft 131 may be formed of a length member having an elliptical or polygonal cross section, and in this case, the rotation block 110 and the eccentric block 120 connected to each other with the connection shaft 131 as a medium can be prevented from being rotated relative to each other about the connection shaft 131.
The eccentric adjusting part 140 includes a connection block 141 connected to the rotation block 110; a first guide member 142 for guiding movement of the connection block 141 in a first axial direction; a second driving part 143 for providing a driving force for moving the connection block 141 in the first axial direction; and a power transmission part 144 disposed between the second driving part 143 and the connection block 141 and converting a driving force provided by the second driving part 143 into a linear motion in a first axial direction of the connection block 141.
Here, it is preferable that the first guide member 142 be formed of an LM guide, and the second driving part 143 be formed of a servo motor for precisely controlling the number of rotations and the rotation angle according to an external input signal.
The power transmission unit 144 includes a ball screw 144a and a ball nut 144b, and the ball screw 144a is disposed in the first axial direction, is supported on the base 210 so as to be rotatable about an axis, and is connected to and rotatable about a drive shaft of the second driving unit 143. The ball nut 144b is coupled to the ball screw 144a and fixed to the connection block 141. In this way, when power is transmitted through the ball screw 144a and the ball nut 144b, the position of the connection block 141 can be precisely controlled, and the position of the connection block 141 does not move at will, so that the interval between the rotation block 110 and the eccentric block 120 can be prevented from being adjusted at will.
The first driving part 150 is for providing a driving force for the shaft rotation of the rotating block 110, and includes a driving shaft connected to the central shaft of the rotating block 110, and is preferably formed of a servo motor capable of precisely controlling a rotation speed according to an external signal.
In the drawings, fig. 3 is a perspective view of the camera-shake correction function inspection apparatus according to the present invention, fig. 4 is a front view structural diagram of the camera-shake correction function inspection apparatus according to the present invention, and fig. 5 is a side view structural diagram of the camera-shake correction function inspection apparatus according to the present invention.
The camera shake correction function inspection apparatus 200 of the present invention shown in fig. 3 to 5 includes a base 210, a vibration plate 220, a vibration size adjustment apparatus 100, a vibration absorbing portion 230, and a socket portion 240.
The base 210 is disposed at the bottom of the vibration plate 220, and the vibration plate 220 is guided to move in the second axis direction by a second guide member 221 at the upper side of the base 210. Here, the second guide 221 may be formed of an LM guide.
In order to check the camera shake correction function, the vibration magnitude adjustment apparatus 100 supplies vibration to the camera module, which can easily adjust the magnitude of the vibration, which has been described above, and thus a detailed description thereof will be omitted.
The damper 230 includes a fixed block 231 connected to the eccentric block 120 and a third guide member 232 movably connecting the fixed block 231 to the vibration plate 220 in a third axial direction, and an insertion hole 231a through which the eccentric block 120 is rotatably supported is provided in the fixed block 231. The third guide member 232 may be formed of an LM guide including a guide rail disposed at a side of the vibration plate 220 in a third axial direction, and a moving block having one end connected to the fixed block 231 and the other end slidably connected to the guide rail along the guide rail.
That is, the eccentric mass 120 rotates around the center axis of the rotating mass 110, and provides the second axis and third axis kinetic energy to the fixed mass 231 of the damper portion 230, and the third axis kinetic energy of the eccentric mass 120 is offset by the third guide member 232 of the damper portion 230, so that only the second axis kinetic energy can be transmitted to the diaphragm 220. Accordingly, the vibration plate 220 can be reciprocated in the second axis direction to provide vibration, and the vibration frequency of the vibration plate 220 can be controlled by controlling the rotation speed of the first driving part 150.
In particular, since the kinetic energy in the second axis direction supplied from the first driving portion 150 to the vibration plate 220 is in the form of a sine curve, feedback of inertia is easily controlled during conversion of the movement direction, and thus stable driving can be achieved even at a high vibration frequency.
The rotating block 110 and the eccentric block 120 are connected to a connection shaft 131 which is disposed to be inclined with respect to the first axial direction, and since the connection block 141 supporting the rotating block 110 is guided by the second guide member 221 to move in the first axial direction, the shock absorbing part 230 supporting the eccentric block 120 is guided to move in the third axial direction, the interval adjustment between the rotating block 110 and the eccentric block 120 by the eccentric adjusting part 140 can be achieved only in a state in which the central axis of the rotating block 110 and the central axis of the eccentric block 120 are aligned with each other in the third axial direction. In addition, mark lines may be formed on the fixed block 231 of the shock absorbing part 230 and the eccentric block 120, respectively, and the mark lines may indicate an aligned state of the central axis of the rotating block 110 and the central axis of the eccentric block 120 in the third axis direction.
The socket 240 is configured to be capable of mounting a camera module and is electrically connectable to the camera module so as to be capable of supplying power to the camera module and inputting and outputting a control signal.
In addition, although the vibration plate 220 is illustrated as linearly reciprocating on the base 210 in the second axial direction to provide vibration in the horizontal direction in the present embodiment, a vibration mechanism for providing vibration caused by movement such as yaw (yaw), pitch (pitch), etc. may be further disposed between the vibration plate 220 and the socket part 240.
An explanation will now be given of the operation of the vibration size adjusting device of the present invention and the camera shake correction function inspection device using the same.
In the drawings, fig. 6 is a diagram showing the vibration action of the camera shake correction function inspection apparatus according to the present invention, and fig. 7 is a diagram showing the action of the eccentricity adjustment section 140 of the camera shake correction function inspection apparatus according to the present invention.
First, as shown in fig. 6 (a), the vibration plate 220 is supported so as to be movable in the second axial direction with respect to the base 210 by the second guide member 221, the rotating block 110 is connected to the first driving unit 150 in a state of being arranged in the first axial direction, the eccentric block 120 is connected to the fixed block 231 of the damper unit 230 at a position eccentric from the rotation center of the rotating block 110, and the fixed block 231 is connected so as to be movable in the third axial direction with respect to the vibration plate 220 by the third guide member 232 of the damper unit 230.
In this state, as shown in fig. 6 (b), (c) and (d), when the first driving part 150 is driven to rotate in one direction, the kinetic energy in the second and third axial directions is generated as the eccentric mass 120 eccentric from the rotation center of the rotating mass 110 rotates, and the kinetic energy in the third axial direction is offset by the movement in the third axial direction of the shock absorbing part 230, and the kinetic energy in the second axial direction is transmitted to the vibration plate 220, so that the vibration plate 220 vibrates while reciprocating in the second axial direction on the base 210 according to the eccentric amount of the rotating mass 110 by the eccentric mass 120.
In addition, the eccentric amounts of the rotating block 110 and the eccentric block 120 may be adjusted by the eccentric adjusting part 140.
Specifically, as shown in fig. 5, the connection block 141 of the eccentric adjustment portion 140 is configured to be movable in the first axial direction on the base 210 by the first guide member 142, and is connected to the second driving portion 143 by the power transmission portion 144, and the position in the first axial direction is adjustable by the driving control of the second driving portion 143.
Specifically, the ball screw 144a of the power transmission unit 144 is disposed on the base 210 so as to be rotatable in the axial direction in a state of being disposed in the first axial direction, and is rotatable in the forward and reverse directions by receiving a driving force from the second driving unit 143. The ball nut 144b coupled to the ball screw 144a is connected to the rotating block 110 through the connection block 141.
The connection shaft 131 provided in the rotary block 110 is connected so as to be axially movable in the insertion hole 121 of the eccentric block 120 in a state of being inclined with respect to the first axial direction, and the eccentric block 120 is connected to the vibration plate 220 so as to be slidable in the third axial direction by the damper 230.
That is, since the rotating block 110 is connected to the connecting block 141 and the eccentric block 120 is connected to the vibration plate 220 with the damper 230 as a medium, the interval with the eccentric block 120 can be adjusted as the connecting block 141 is moved in the first axial direction by the driving of the second driving part 143.
Next, as shown in fig. 7, when the ball screw 144a is rotated in one direction by the driving of the second driving unit 143 and the ball nut 144b is moved in the arrow direction in the drawing, the rotating block 110 connected to the ball nut 144b via the connecting block 141 is moved in a direction away from the eccentric block 120. At this time, since the rotating block 110 and the eccentric block 120 are connected to each other by the connection shaft 131 arranged to be inclined, the interval between the central axis of the rotating block 110 and the central axis of the eccentric block 120 is similarly pulled apart, and the eccentric amount of the eccentric block 120 rotating around the central axis of the rotating block 110 is increased.
In contrast, when the second driving part 143 performs the reverse driving, the rotating block 110 moves in a direction approaching the eccentric block 120, and thus the eccentric amount of the eccentric block 120 decreases.
As described above, according to the present embodiment, in a state in which the rotating block 110 and the eccentric block 120 are connected by the connecting shaft 131 arranged to be inclined, the interval between the rotating block 110 and the eccentric block 120 is adjusted by the eccentric adjusting portion 140, so that the eccentric amount of the eccentric block 120 rotating about the center axis of the rotating block 110 is adjusted, and thus the magnitude of the vibration applied to the vibration plate 220 can be easily adjusted.
Further, since the rotating block 110 and the eccentric block 120 of the eccentric adjusting part 140 are connected by the connection shaft 131 which is disposed obliquely, and the connection block 141 connected to the rotating block 110 can be moved only in the first axial direction by the first guide member 142, and the eccentric block 120 can be moved only in the third axial direction by the shock absorbing part 230, the interval adjustment between the rotating block 110 and the eccentric block 120 by the eccentric adjusting part 140 is preferably performed in a state in which the central axes of the rotating block 110 and the eccentric block 120 are aligned in the third axial direction. At this time, since the displacement amount of the eccentric mass 120 in the third axis direction generated during the movement of the rotating mass 110 is offset by the movement of the shock absorbing part 230, the position of the vibration plate 220 in the second axis direction can be not changed during the adjustment of the eccentric amount of the eccentric mass 120 by the eccentric adjusting part 140.
The scope of the claims of the present invention is not limited to the above-described embodiments, but may be implemented by various forms of embodiments within the scope of the appended claims. Various modifications of the invention, which are within the scope of the spirit of the invention as claimed in the claims, are possible to those skilled in the art to which the invention pertains, and the scope of the invention is also within the scope of the claims.
